Abstract
Clinicians are growing inured to the fact that rarely do the results of a single randomized controlled trial (RCT) decisively change clinical practice. Nor should they. In a new RCT, Kirke and colleagues have compared the therapeutic effects of different types of UVB radiation on clearance of psoriasis. Their study is unlikely to be the last word on this topic.
